Destiny. Dean was going over Buffy's words as he drove his car down the road. It was a word he couldn't, wouldn't accept in relation to himself. And it didn't even have to do with all of his issues ... which weren't issues but valid reasonings. Instead it had more to do with common sense. Him and Sam? They were Hunters. Not world savers. He had been saying that since he'd been pulled out of hell, instead of having people listening to him, he was getting more and more people telling him the same thing. One after the other. He had a destiny. God had chosen him. He had a responsibility. The world needed him.
Dean didn't know about the world but he had been fighting the monsters since he was a kid. That wasn't going to stop just because some person had decided before he was born that he was meant to do something, to fix their mess because they didn't care enough to do so. He'd fix the mess, he'd stop it. But after that. He was going back to as much of his life as he could. He wasn't made for this destiny bullshit.
It was pure luck really, that Dean was passing a trashcan, rolling his window down when he heard a loud clatter. He wouldn't have been surprised if he had managed to hear it window up. You didn't miss a noise like that. Because it was followed soon by another clatter Dean got out of his car, making sure he had his gun on him and went to check it out. Being sure to put money in the parking meter of course.
He arrived just in time to see Buffy bring her foot down on what he was guessing a demon's back. From what he knew of her, he knew she wouldn't throw a human around like that. As much as he liked the woman, he almost let out a curse. In fact he did. He had been trying to escape her words in his head only to find her.
